VideoActivity.java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_layout);
        mVideoView = (VideoView) findViewById(R.id.video_activity_videoView);
        mMc = new CustomMediaController(this);
        mMc.setFocusable(true);
        mVideoView.setMediaController(mMc);
        mVideoView.setOnFocusChangeListener(new OnFocusChangeListener() {                               
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    if (mMc != null) mMc.show(5000);
                } else {
                    if (mMc != null) mMc.hide();
                }
            }
        });

        mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()  {
            @Override
            public void onPrepared(MediaPlayer mp) {                         
                if (Constant.DEBUG) Log.d(TAG, "Duration = " + mVideoView.getDuration() 
                        + ", Type = " + mType + ", mHasPermission = " + mHasPermission); 
                if (mTimer == null && mHasPermission == false) {
                    mTimer = new Timer(true);
                    mTimer.schedule(new timerTask(), 1000, 1000);
                }   

                mp.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {                   
                    @Override
                    public void onBufferingUpdate(MediaPlayer mp, int percent) {
                        if (Constant.DEBUG) Log.d(TAG, "percent = " + percent);
                        if (mIsReady == false) {
                            mIsReady = true;
                         mVideoView.setBackgroundColor(getResources().getColor(R.color.none));
                        ProgressBar progressBar = (ProgressBar) findViewById(R.id.video_activity_progressBar);
                        if (progressBar.getVisibility() != View.GONE) progressBar.setVisibility(View.GONE);
                        }
                    }
                });
            }
        });

        mType = getIntent().getIntExtra("type", Constant.PRG_TYPE_CHARGE);
        mHasPermission = getIntent().getBooleanExtra("permission", true);
        mId = getIntent().getStringExtra("id");
        String playTime = getIntent().getStringExtra("play_time");
        if (playTime != null) {
            mPlayTime = Integer.valueOf(playTime) * 1000;
            Log.d(TAG, "mPlayTime = " + mPlayTime);
        }
        mString = getIntent().getStringExtra("url");
        if (mString == null) {
            finish();
        } else {
            mVideoView.setVideoURI(Uri.parse(mString));
            if (mPlayTime != 0) {
                showContinueDialog();
            } else {
                mVideoView.requestFocus();
                mVideoView.start();     
            }
        }
    }

Any help would be appreciated. Thank you.

have you tried testing it on other devices? or just with the two devices you mentioned? – Pastore

thanks for your kindness! I tested in two smart box and one Samsung Galaxy TabPro,one of the smart box got this issue。 – Campy

Usually this kind of bugs are hardware dependent so it depends on the device used in testing. If you can test it in say at least 3 more devices then we can tell if this is a hardware dependent bug or a real software bug. Is it possible to test in more devices? – Pastore

on first glance the code seems okay. can't run it now though, no IDE on my current device. – Pastore

Yes you are right,I should test in more devices to see if this is a software bug. But I also used the original player in the smart box which has issue run our app to play the same video, the original player can play it without any issues.So I think this issue may caused by our app code. – Campy
